The AES Corp. has announced the commercial operation of its 40 MW energy storage resource in Moraine, Ohio.

Located at Dayton Power and Light's (DP&L) Tait generating station, the project is providing fast-response frequency regulation services to PJM Interconnection to help stabilize the grid, according to AES.

"Advanced energy storage resources can uniquely maximize the performance and efficiency of the grid through their ability to act as both generation and load," says AES' Phil Herrington. "With over 100 MW now serving the PJM market, we are seeing a growing interest from AES customers in other key markets."

AES notes that the Tait battery array includes more than 800,000 battery cells and connects through DP&L Tait station's transformers, operated by DP&L and DPL Energy LLC, through an independent agreement with PJM.
